纤维和蛋白质对肠道健康和环境的影响

由于膳食纤维和蛋白质对肠道健康和环境都有潜在的有益或有害影响,因此,膳食纤维和蛋白质在猪肠道中的发酵是一个值得关注的问题.本文综述了近年来有关膳食纤维和蛋白质发酵对猪肠道环境的影响及其对猪粪和猪舍含氮气体和异味排放的影响,同时探讨了蛋白质发酵和相关代谢化合物的生产,与膳食纤维发酵、对肠道健康、细菌蛋白质合成和氮排泄的影...

Effects of fiber and protein on intestinal health and the environment

The fermentation of dietary fiber and protein in the intestine of pigs is of concern because of their potential beneficial or harmful effects on intestinal health and the environment.In this paper,the effects of dietary fiber and protein fermentation on intestinal environment of pigs and on nitrogen gas and odor emission in pig manure and pigsty in recent years were reviewed,and the effects of protein fermentation and related metabolites production and dietary fiber fermentation on intestinal health,bacterial protein synthesis and nitrogen excretion were discussed.In response to the negative environmental impacts of intensive pig production,different nutritional strategies,such as reducing dietary crude protein levels to reduce nitrogen excretion,were used.Overall,dietary fiber and low protein levels are an effective nutritional strategy for reducing nitrogen excretion and environmental adverse effects of intestinal fermentation in pigs.
